I lived this concept, but the execution is subpar. The plastic grinder isn't nearly as effective or easy to use as a metal grinder, so I stopped using it after the first few tries. But the concept of having a stage just attached to the grinder is nothing short of brilliant. If I could find one of these in metal compatible with a mason jar, I'd buy it right away.Off to go search for that!

Best grinder I’ve bought, hands down 🙌 You just screw it onto a mason jar of your choice and grind away. It’s so easy! You do have to soak it in alcohol to get your sticky herbs…lol…off when it becomes harder to grind (twist) your stuff. Great value, compared to other metal grinders.

I got into blunts recently because my state legalized, I started growing and need new forms of smoking!! anyways… this thing grinds to the perfect blunt texture + it goes straight into the jar!! so you can really grind a lot! love the grinder, I just ask.. for the resin build up on the grinder itself, is it okay to use metal to get it off?Thank you for this creation!

I got the small grinder with holes and put it on a Ball 4oz jelly jar. It works perfectly, turns smoothly, and can grind large amounts of hemp quickly compared to my previous grinder, directly into a perfect storage container. Of course, the larger grinder could make the process even faster. I'd like to see a stainless steel model, but this one will work for now.

So far so good, it is able to grind up dried basil and dried mint fairly well.I will say one improvement would be that it could have sharper "teeth" to grind things up more quickly. Not a big thing, it just takes some time to grind.I'd also like to see a CNC or milled metal version of this!
